The relationship of the shale allochton and carbonate parautochton of Pay-Khoy (Ugra peninsula)

Tectonic relationship of the shale allochton and the carbonate parautochton of Pay-Khoy is subject of debates. Detailed study of the geological composition of the area of allochton and parautochton junction in the North of Pay-Khoy (Cape of Pyrkov, Lake of Khaenato, village of Khabarovo) demonstrates the presence of a number of klippes composed of deep-water sediments of the Early Palaeozoic age. Analyses of morphology and orientation of folds and faults show that the Main thrust fault of Pay-Khoy is accompanied by the formation of overthrust with minimum amplitude of movement on subhorizontal surface of more than 5 kilometers. The indications of the nature of the thrust suggest the presence of the deep-water facies sedimentary klippes in the south of the island of Vaigach. Carbonate parautochton was heavily deployed and undergone the same complicated way of tectonic transformations, as the allochton.
